Vacuum Seal and O-Ring Grease
A firm consistency and resistance to evaporation make this grease ideal for vacuum applications, such as flow meters, vacuum and pressure systems, and laboratory equipment. Apply directly to seals and O-rings to prevent drying and cracking.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening and is comparable to Fomblin grease. NLGI 3.5 is between the consistency of vegetable shortening and frozen yogurt.
Grease with PTFE thickener resists aggressive acids, bases, and solvents. Chemours Krytox™ 240 grease is long lasting with an indefinite shelf life.
Grease lubricates most efficiently below the maximum temperature. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.

Vacuum Pump Oil
For long-lasting lubrication in vacuum pumps, this oil is slow to evaporate.
Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows.
Chemours Krytox™ oil is chemically inert, can be used with oxygen, and is long lasting with an indefinite shelf life.
